I'm also not keen on the Juggluco screen, so I never look at it aside from when I pair a sensor, I always look at the XDrip+ display.
Agreed that XDrip+ has taken on lots of functionality, it would IMO be better to separate functionality out into different apps so that replacements for different aspects are easier to develop and integrate into a "system" (e.g. food tracking, BG prediction, calibration.)
I will eventually get around to finishing an app to handle some part of the functionality, but life gets in the way (and Google/Android change their API/recommendations quite often and it's then back to trying to work out how to move to the new flavour!)
